DISSERTATION TU DRESDEN MASCHINENWESEN

Every year, nearly young scientists enter doctoral and post-doctoral programmes at the Department of Mechanical Engineering, with more than 20 percent being women – an increasing trend. The Graduate School is the central hub of contact for all doctoral students and post-doctoral students for all questions concerning the doctoral and postdoctoral phase of their studies at TU Dresden. This information is available in German only. For more information, please contact our Alumni Officer. In terms of nanotube orientation, different techniques have been demonstrated for the fabrication of horizontally aligned SWCNTs with either post synthesis routes e. Skip to main navigation. You can also decide for publishing in print or with a publisher.

Thus, the catalyst-free synthesis of aligned SWNT is very desirable. It is shown, for the first time, how one can grow horizontally aligned carbon nanotubes in crossbar configurations in a single step and with bespoke crossing angles. Also of fundamental importance is to revisit well-established synthesis techniques employing a new set of materials as precursors, substrates and catalysts. Address parcel Parcel Address: These CVD techniques suffer some drawbacks, namely, that because they are synthesized using catalyst particles metals or non-metals the catalyst material can contaminate the tubes and affect their intrinsic properties.

This information is available in German only.

There are different ways to publish a doctoral thesis. The process was carried out at room temperature and inside a transmission electron microscope. Learn more about admission requirements, guidelines and regulations. In addition, the transport properties of the aligned tubes at room temperature are also investigated through the fabrication of devices based on these tubes.

This information is provided by FIS. Subsequently, the unsteady behaviour of the blade boundary layer will be considered. The award is one of the most highly revered prizes for final theses at the TU Dresden.

Materials Science and Engineering Innovative material systems and their production technologies in a cross-material and cross-product approach are at the centre of a long tradition and excellent expertise at TU Dresden. Fundamental breakthroughs in the field of nanotechnology can be achieved by developing new synthesis procedures as well as by adapting known procedures to new materials.

In this direction, a strategy for alignment of carbon nanotubes at liquid-liquid interfaces using dielectrophoresis is also investigated. Maschineenwesen of the TU Dresden The TU Dresden has passed a Resolution on Open Access-Publishing that explicitely calls researchers to make their scientific work accessible to the public maschinenweswn publishing on the institutional repository Qucosa.

The process is enhanced by a high temperature and the presence of pre-existing superficial defects cracks, terraces, etc. With increasing aerodynamic loading of the blades and higher Mach numbers the consideration of rotor-stator-interactions gains in importance.

Also of fundamental importance is to revisit well-established synthesis techniques employing a new set of materials as precursors, substrates and catalysts.

Amongst others, these are geometrical parameters like the blading geometry and the axial gap width. As a result, the real flow field is highly periodically unsteady and very complex, especially in multistage turbomachinery. The aim of this work is to develop new strategies for alignment by self assembly of such one-dimensional masfhinenwesen like carbon nanotubes using combination of different conventional techniques.

Thus, the catalyst-free synthesis of aligned SWNT is very desirable. Innovative material systems and their production technologies in a cross-material and cross-product approach are at the centre of a long tradition and excellent expertise at TU Dresden.

Assembly of nanoparticles provides effective building blocks for physical, chemical and biological systems which have surprisingly collective intrinsic physical properties. Skip to main navigation.

The ceremonial conferring of the doctoral and post-doctoral degrees takes place every year on the “Faculty of Mechanical Engineering Day”. Their high charge mobility, exceedingly good current-carrying capacities dossertation ability to be either semiconducting or metallic render them ideal building blocks for nanoelectronics. The novelty of the work relies on the formation mechanism of the Al5BO9 nanowires.

It is observed in several studies, that the profile losses and hence the compressor performance of embedded stages are altered compared to isolated blade rows due to blade row interaction effects. For more information, please contact our Alumni Officer. In the second part, first-principle theoretical calculations of the self-assembly properties and electronic structure of Ferrocene-functionalized complexes have been carried out.

In addition, the wakes and potential effects superimpose with other flow patterns, for instance the tip clearance vortices and other secondary flow phenomena. The main emphasis is given to study the interaction between localized charge-carrier molecular states and the delocalized surface states. The results of these calculations demonstrate the possibility to obtain real systems in which intra-molecular charge localization can be combined with self-assembly scaffolding and absorbed on either Highly oriented pyrolytic graphite HOPG or metallic-surfaces.

After you have made a decision on how to publish, please ask at your faculty about the according guidelines. Skip to main navigation.
